D E B U G G E R  14  Walk  (F6).  Start  low-speed  step-by-step  target  program  execution  with  the  same  timing,  as  for  the Snapshot  command.  During  Walk  process  you  can  change  any  registers  and  variables  and  therefore immediately change program flow. Step (F7). This key activates one command execution. Step Over (F8). This key adds dynamic breakpoint on the next to the current P& command and therefore omit one command. It allows step-by-step debug without subroutines or unwanted branches execution. This function will not affect watchpoint or breakpoint already set in program. Real Time Run. Switch on this key, when you use Realtime module and want to define target SX clock source  and  frequency  (see  &hapter  2  for  details).  Switch  off  this  key,  if  you  use  only  SX-TIPS  debugger/ programmer without Realtime module.  New  Watch  Window  (ctrl+N).  Open  Watch  &onstructor  window  to  create  new  Watch  Window.  See &hapter 7 for detailed Watch &onstructor description. Run Time Measurement. This is tool for code fragment run time counting. To measure time, Jump to &ursor and Run to &ursor commands from the pop-up menu can be used. Set target SX program counter (P&) with the command Jump to &ursor to the first command of the measured fragment. Than place cursor to the next command after the last executed command of the measured fragment and activate Run to &ursor command.  Last  executed  command  will  be  Breakpoint  command;  this  command execution time did not counted. Real time measurement can work only with Real Time Run button switched off, with low-speed clock about 170 kHz, generated by SX-TIPS debugger/programmer. Popup window In  Debug  mode  popup  window  on the right mouse click available in the source and listing windows. Most functions are the same, as in the Debug mode toolbar. Some functions were available only in the popup window. Jump  to  &ursor.  This  function  load  new  value  into  the target  SX  microcontroller  program  counter  (P&).  This  is address of the command, currently pointed in the source or listing window. All other registers content did not changed. Run to &ursor. This function set dynamic breakpoint at cursor position in the source or listing window and activate Run command. Target SX microcontroller will run from its previous state till the new breakpoint. This function will not affect watchpoint or breakpoint already set in program.
